Title: Electrically erasable, directly overwritable, multibit single cell memory elements and arrays fabricated therefrom.
Inventor: OVSHINSKY STANFORD R
IPC: H01L45/00
Filed: 1992-08-17
Abstract: A solid state, directly overwritable, non volatile, high speed, multibit single cell memory characterized by numerous stable, non volatile detectable configurations of local atomic and/or electronic order, which can be selectively and repeatably accessed by electrical input signals of varying pulse voltage and duration. There is also disclosed a unique class of microcrystalline semiconductor materials which can be modulated, within a crystalline phase, to assume any one of a large dynamic range of different Fermi level position while maintaining a substantially constant band gap over the entire range, even after a modulating field has been removed. The memory elements are characterized by enhanced stability, achieved through the use of compositional modulation of the semiconductor material from which the memory elements are fabricated. The memory elements may include an electrical contact formed of amorphous silicon, either alone or in combination with a layer of amorphous carbon. The memory elements (30) may be in the form of regions (36) of memory material surrounded by oxide layers (20, 39). The memory elements may be in the form of an array having access diodes formed between N type layers (18) and P type regions (24), with the elements located at the intersections of row lines formed by N + regions (12) and column lines (42).

Title: Tubular furnace and method of controlling combustion thereof.
Inventor: MIYAMA HIROSHI
IPC: C10G9/20
Filed: 1992-10-30
Abstract: A tubular furnace of such an arrangement that, while a fluid to be heated can be prevented from coking or a heating pipe can be prevented from burning, a predetermined quantity of heat is provided through a smaller heat transfer area and problems of corrosion at low temperature of the heating pipe in the tubular furnace due to sulfur contents in the fuel are solved, to thereby achieve a high efficiency. In this tubular furnace (1), a coil path (3) is divided into a plurality of zones (2, ..., 2); at least one heat accumulator type burner system (4) is provided in each of the zones (2, ..., 2) for alternately performing the supply of combustion air to burners (5, 6) through heat accumulators (7, 7) and the discharge of combustion gas therefrom; a combustion quantity is independently controlled in each of the zones (2, ..., 2), so that a desirable heat flux pattern can be formed such that a boundary layer temperature of the fluid to be heated in the zones (2, ..., 2) of the coil path (3) is lower than a coking temperature or lower than an allowable maximum temperature to be determined by the material for use in the heating pipe, and is set substantially the same in all of the zones. With this arrangement, the heat flux is increased at the inlet zone where the temperature is well below a coking temperature, while coking is prevented; a predetermined quantity of heat is provided through a smaller heat transfer area; the temperature of the tubular wall at the inlet zone is raised to avoid the corrosion at low temperature; the waste heat of the waste combustion gas is utilized to preheat the combustion air so as to achieve a thermal efficiency as high as that in a furnace provided with a convection section, even without a convection section, so that it becomes possible to render the furnace compact in size or to increase the treating quantity.

Inventor: HAMMERSMARK DAN J
IPC: A61B19/00
Filed: 1993-03-17
Abstract: Cette invention concerne un cathéter (10) pourvu d'une extrémité pouvant subir une torsion. Le cathéter comportant une paroi souple destinée à être utilisée dans une anatomie à torsion complexe comprend un fil de torsion (50) ou un orifice (20) de fil de guidage pouvant subir une torsion. Le fil de torsion ou l'orifice de fil de guidage pouvant subir une torsion s'étend sur la longueur du cathéter et se trouve attaché au cathéter au niveau de son extrémité distale ou à proximité de cette dernière. Le côté distal du cathéter est biaisé de manière à ce que le cathéter s'aligne automatiquement avec un obstacle lorsqu'on l'introduit. L'extrémité proximale du fil de torsion dépasse de l'extrémité proximale du cathéter et se trouve attachée à un limiteur de rotation (130). La rotation du limiteur de rotation applique une torsion sur le fil de torsion ou sur l'orifice du fil de guidage pouvant subir une torsion, cette torsion étant transmise dans le cathéter jusqu'à l'extrémité distale du cathéter au niveau de laquelle la torsion appliquée fait tourner l'extrémité distale pour permettre d'aligner mmanuellement l'extrémité avec un obstacle.

Title: Inhibition of the formation of nitrosamines.
IPC: C07C291/04
Filed: 1993-04-28
Abstract: Reaction of amine-containing substrates with hydrogen peroxide can suffer from certain problems, especially in the presence of transition metals. These problems include both in situ generation of impurities and particularly nitrosamines, which are allegedly carcinogenic, and also impaired product formation. The problems can be ameliorated by employing in the reaction mixture free radical scavengers, including in particular phenols and polyhydroxy-substituted aromatic compounds. The scavengers are advantageously employed in conjuction with a metal chelating agent such as polycarboxylic acid or an organopolyphosphonic acid.

Title: Self-protecting irrigation hose and method.
Inventor: DE FRANK MICHAEL P
IPC: B05B1/20
Filed: 1994-02-03
Abstract: In a method for protecting an irrigation hose from attack by the elements, an elongated flat sheet of flexible water impervious plastic film (12) is bent along its length to form an overlapping longitudinal seam between opposing longitudinal margins of the sheet. The longitudinal seam is sealed with first and second rib like adhesive beads (16, 18) extending longitudinally uninterrupted along the opposing margins of the sheet in spaced apart relationship to form a continuous chemical storage channel (22) defined by the beads and the opposing margins and to form a water supply channel (24) defined by the remainder of the sheet. The chemical storage channel is fluidically isolated from the water supply channel. The sheet is laid on or under the ground. The ends of the chemical storage channel are sealed so (Fig. 6) that the only means of egress therefrom is through the interstices of the material of the sheet and the beads. A hose protecting chemical is injected into the chemical storage channel (Fig. 5). The irrigation hose is put into service by pressurizing the water supply channel. The hose protecting chemical defuses slowly through the interstices of the sheet material so as to protect the exterior surface of the hose from insects, root intrusion, and/or other damaging environmental conditions.
